KI 2008 was the 31st Annual German Conference on Arti?cial Intelligence held September 23-26 at the University of Kaiserslautern and the German Research Center for Arti?cial Intelligence DFKI Gmb H in Kaiserslautern, Germany. The conference series started in 1975 with the German Workshop on AI (GWAI), which took place in Bonn, and represents the ?rst forum of its type for the German AI Community. Over the years AI has become a major ?eld in c- puter sciencein Germanyinvolvinga numberof successfulprojects thatreceived much international attention. Today KI conferences are international forums where participants from academia and industry from all over the world meet to exchange their recent research results and to discuss trends in the ?eld. Since 1993 the meeting has been called the "Annual German Conference on Arti?cial Intelligence, " designated by the German acronym KI.

Becauseofthis, thechoice of presentation form (oral, poster) was based on how well reviews indicated that the paper would ?t into one or the other format. The proceedings allocate the same space to both types of papers. In addition, we selected six papers that show high application potential – scribing systems or prototypical implementations of innovative AI technologies. They are also included in this volume as two-page extended abstracts.
